Abstract

The invention discloses a piston facilitating demounting. The piston comprises a piston cap. The piston cap is of a hollow structure, and a through hole communicating with the outer portion is formedin the upper end of the piston cap. A sealing cover matched with the through hole is arranged at an opening of the through hole. A mounting block is arranged in the piston cap. Fixed devices are arranged on the side walls of the two sides of the mounting block. A connecting rod is rotationally connected to the mounting block and penetrates the lower end of the piston cap. The end, away from the mounting block, of the connecting rod is rotationally connected with piston rings. The piston rings comprise the first piston ring and the second piston ring. Two symmetric first threaded rods are vertically arranged on the first piston ring, and the two first threaded rods both penetrate the first piston ring. Threaded holes matched with the first threaded rods are formed in the second piston ring.The components of the piston are convenient to demount, and accumulated carbon in the components of the piston can be cleared away conveniently.

Description

technical field [0001] The invention relates to the technical field of pistons, in particular to a piston that is easy to disassemble. Background technique [0002] The piston is a reciprocating part in the cylinder block of an automobile engine. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected form of the combustion chamber. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat-absorbing areas. There are often various pits on the top of the piston of a diesel engine, and its specific shape, position and size must be adapted to the requirements of the mixture formation and combustion of the diesel engine. [0003] When the piston is in use, carbon deposits are generated when the engine oil burns, so it needs to be cleaned regularly. Most of the existing piston parts are fixedly connected, which is inconvenient ...
